BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a liquid crystal display device (LCD),and more particularly, to a liquid crystal display device havingdielectric frames of which dielectric constant is different from that ofliquid crystal

2. Description of the Related Art

Recently, a LCD has been proposed where the liquid crystal is notaligned, and the liquid crystal is driven by common electrode 17 havingopen areas 19. FIG. 1 is sectional view of pixel unit of theconventional LCD.

Regarding conventional LCDs, a plurality of gate bus lines arranged in afirst direction on a first substrate and a plurality of data bus linesarranged in a second direction on the first substrate divide the firstsubstrate into a plurality of pixel regions.

A thin film transistor (TFT) applies image signal delivered from thedata bus line to a pixel electrode 13 or a passivation layer. The TFT isformed on each pixel region and comprises a gate, electrode, a gateinsulator, a semiconductor layer, an ohmic contact layer, a sourceelectrode, and a drain electrode, etc.

Alternatively, a passivation layer is formed over the whole firstsubstrate, and pixel electrode 13 is connected to the drain electrodethereon.

On a second substrate, a light shielding layer 25 is formed to shieldany light leakage from gate and data bus lines, and the TFT, a colorfilter layer 23 is formed on the light shielding layer, an over coatlayer 45 is formed on the color filter layer, a common electrode 17 isformed to have open area 19 on the over coat layer, spacers 51 aredispersed to maintain the gap between the first and second substratesthereon, and a liquid crystal layer is formed between the first andsecond substrates.

Pixel electrode 13 and open area (slit) 19 of the common electrode 17distort the electric field applied to the liquid crystal layer Then,liquid crystal molecules are driven variously in a unit pixel. Thismeans that when voltage is applied to the LCD, dielectric energy due tothe distorted electric field arranges the liquid crystal directors inneeded or desired positions.

In the LCDs, however, open area 19 in common electrode 17 or pixelelectrode 13 is necessary, and the liquid crystal molecules could bedriven stably when the open area is wider.

If the electrodes do not have an open area or the width of the open areais narrow, the electric field distortion needed to divide the pixelregion becomes weak.

And, distillation occurs from the area where the liquid crystaldirectors are parallel with a transmittance axis of the polarizer, whichresults in a decrease in brightness. Further, according to the surfacestate of LCDs, the liquid crystal texture has an irregular structure.

Moreover, because spacer 51 is not fixed and is mobile, there is problemthat the distribution of the spacers is not uniform in the LC cell.

On the second substrate 33, a light shielding layer 25 is formed toshield any light leakage from gate and data bus lines, and the TFT. Acolor filter layer 23 is formed R, G, B (red, green, blue) elements toalternate on the light shielding layer. A common electrode 17 is formedwith ITO on the color filter layer.

The compensation film is a negative uniaxial film, which hasone optical axis, and compensates the phase difference of the directionaccording to viewing-angle. Hence, it is possible to compensateeffectively the right-left viewing-angle by widening the area withoutgray inversion, increasing contrast ratio in an inclined direction, andforming one pixel to multi-domain.

In the present multi-domain liquid crystal display device, it ispossible to form a negative biaxial film as the compensation film 29,which has two optical axes and has wider viewing-angle characteristicsas compared with the negative uniaxial film. The compensation film couldbe formed on both substrates or one of them.

Furthermore,neighboring two pixels and two alignment directions are associated,which obtains multi-domain effect. Although not shown in the figures,there are embodiments that do not form the auxiliary electrode 27

The solid lined-arrow 67 presents the alignment direction of the secondsubstrate 33 and the dotted lined-arrow 65 presents the alignmentdirection of the first substrate 31.

In the FIGS. 11A, 11B, and 11C, the auxiliary electrode 27 is formed,and the dielectric frame 57 is patterned in various shapes. Furthermoreneighboring two pixels and two alignment directions are associated beingdifferent from that in the FIG. 10, which obtains multi-domain effect.Although not shown in the figures, there are embodiments that do notform the auxiliary electrode 27.

In the LCD in FIGS. 9 to 11, the liquid crystal layer includes liquidcrystal molecules having positive dielectric anisotropy, which applies ahomogeneous alignment where liquid crystal molecules in the liquidcrystal layer are aligned homogeneously to surfaces of the first andsecond substrates.

From forming the electric field inducing window or dielectric frame, themulti-domain is obtained by dividing each pixel into four domains suchas in a “+”“x”, or “double Y” shape, or dividing each pixelhorizontally, vertically, and/or diagonally, and differentlyalignment-treating or forming alignment directions on each domain and oneach substrate.

Furthermore, in multi-domain LCD of the present invention, the first andsecond alignment layers 53, 55 are formed over the whole first and/orsecond substrates. The alignment layer includes a material such aspolyamide or polyimide based materials, PVA (polyvinylalcohol), polyamicacid or SiO₂. When rubbing is used to determine an alignment direction,it should be possible to apply any material suitable for the rubbingtreatment.

Moreover, it is possible to form the alignment layer with aphotosensitive material such as PVCN (polyvinylcinnamate), PSCN(polysiloxanecinnamate), and CelCN (cellulosecinnamate) based materials.Any material suitable for the photo-aligning treatment may he used.Irradiating light once on the alignment layer determines the alignmentor pretilt direction and the pretilt angle. The light used in thephoto-alignment is preferably a light in a range of ultraviolet light,and any of unpolarized light, linearly polarized light, and partiallypolarized light can be used.

In the rubbing or photo-alignment treatment, it is possible to apply oneor both of the first and second substrates, and to apply differentaligning-treatment on each substrate.

From the aligning-treatment, a multi-domain LCD is formed with at leasttwo domains, and LC molecules of the LC lager are aligned differentlyone another en each domain. That is, the multi-domain is obtained bydividing each pixel into four domains such as in a “+” or “x” shape, ordividing each pixel horizontally, vertically, and/or diagonally, anddifferently alignment treating or forming alignment directions on eachdomain and on each substrate.

It is possible to have at least one domain of the divided domainsunaligned. It is also possible to have all domains unaligned.

Consequently, the multi-domain LCD of the present invention formsdielectric frames of which dielectric constant is different from that ofliquid crystal, and auxiliary electrode or electric field inducingwindow to distort electric field, thereby wide viewing angle isobtained.

Also, the dielectric frame is patterned as a spacer, which an leave outthe spacer process in the conventional LCD process.

Furthermore, in the case of conducting an alignment-treatment, a highresponse time and a stable LC Structure can be obtained by a pretiltangle and an anchoring energy.
